Paint, poly-hydroxy-functional polysiloxane, their preparation and use as an anti-blocking agent and anti-fouling agent in the polymer molding materials and thermoplastics

摘要

It is possible to provide paint compositions which exhibit (dirt-repellent) acting anti-fouling and anti-adhesive effect and / or that have been [problem] improvement, thermoplastic polymers and plastics molding material. A process for preparing polyhydroxy-functional polysiloxanes containing [SOLUTION] branched polyglycidol polyether radical, first, it reacts with the carbonate glycidol or glycidol at least one methallyl starting compounds allyl or at least one and thereby, to form a methallyl polyether allyl polyether which is modified with a branched polyglycidol one or more radicals, then, methallyl polyether or one or more allyl polyether of one or more thus prepared in the presence of an acid buffer, Si-H-functional alkyl, - coating composition comprising the polysiloxane wherein the be subjected to addition reaction with the polysiloxane, and the polysiloxane obtained by the method, is an additive for thermoplastics or polymer molding material.
